ABSTRACT:
This invention enables production of N-alkylated amines without the use of high pressures, and with high recovery, by continuous single-step reaction of an alcohol with either ammonia or a primary or secondary amine, in vapor phase, through the discovery that thorium sulfate, used as a catalyst for the first time in said reaction, enables discard of high pressures, reaction at atmospheric pressure or thereabout, and the use of simple equipment and low labor cost.
